  Hi,
  
  i hope some1 out there can shed some light on the topic i mentioned above.
  
  I am a japanese car fanatic, i also hope those car enthusiasts driving a WRX/Evo 7/8/MR / DC-5/ 350z/ rx-8 etc can share ur experience in driving the car. THnks a lot.... Have a nice day to all !!!

  its not A turbo lag. it's just "turbo lag"
  
  turbo lag is what happens when a car with a turbocharged engine is in the incorrect RPM range, as a result the exhaust gases are not powerful enough to spool the turbo turbine up. Due to the low compression ratio of TCed engines, this results in a much slower increase in engine RPMs than in naturally aspirated engines. This lag b4 the turbo spools up and while the engine feels lethargic and slow is termed "turbo lag"

  in easy style is...
  
  turbo need (charge pressure=air) to turn the "fan=propellar" inside the turbo..
  
  hence when if u at low rpm even u floor the acc, u only see smoke...cos is oil go in engin & not enough air...so no gd combustion lor...
  
  So turbo lag bascially mean u dun hv enough dense air & low rpm den will kanna lor.. if not.. it will be wicked..lolx.

  the time before a turbocharger spools... time varies from inertia of the turbo fan to the amount of exhaust gases released from the engine...

  Turbo lag:
  
  caused by turbines in turbochargers..depends wat turbo u use..smal turbocharger has small turbines and when it spins,it will have less inertia and travelling at low speeds is the best using a small turbocharger but when at high speed.cant bring out the maxmium torque.
  
  other way round is the large turbocharger is via versa from small turbocharger.
  Turbine need time to spin when u shift and that time taken is wat we call turbo lag.
